Beschreibung
Zusammenfassung:	The present invention relates to a method for preparing an aqueous dispersion of opacifying pigment-binder hybrid particles that provides particle swelling and concomitant introduction of a binder layer without inhibition of polymerization. The composition prepared by the process of the present invention is useful for reducing the level of TiO2 in paints. La présente invention concerne un procédé de préparation d'une dispersion aqueuse de particules hybrides liant un pigment opacifiant qui permet un gonflement des particules et l'introduction concomitante d'une couche de liant sans inhibition de la polymérisation. La composition préparée selon le procédé de la présente invention est utile pour réduire le niveau de TiO2 dans des peintures.
